DanarchyJaml

dAnarchy Jaml converts YAML files to JSON and JSON files to YAML. This assumes a standard YAML or JSON formatted file and does not accept files containing specialized functions like AWS Cloudformation templates.

Add this line to your application's Gemfile:

gem 'danarchy_jaml'

And then execute:

$ bundle

Or install it yourself as:

$ gem install danarchy_jaml

~$ danarchy_jaml /tmp/file1.yaml /tmp/file2.json
